Genuine REVHIGH PCV Valve Breather Repair
Revhigh is proud to introduce our revised PCV Valve Breather Repair designed for selected GM 3.0L and 3.6L V6 engines.
This upgraded PCV solution is designed to improve crankcase ventilation and airflow while addressing common issues associated with the original factory-style PCV breather design.
Available applications include selected Holden, Chevrolet, Buick, Pontiac, Cadillac and other GM vehicles fitted with compatible 3.0L and 3.6L V6 engines.
Important PCV Information
Please note that this PCV unit is a restrictor-style valve, not a one-way check valve.
Therefore, it is normal to be able to pass air through the valve from both ends. The purpose of this design is to regulate and restrict airflow, rather than completely open or close like a traditional one-way check valve.
This is a revised PCV design featuring larger breather holes to improve airflow and engine breathing.
The revised breather holes are approximately 1mm larger than the factory version, providing a more efficient airflow path compared with the OEM-style design.
The design has been tested and refined to help reduce the likelihood of clogging and unwanted crankcase ventilation issues, while maintaining the required restriction for the engine's PCV system.
